DESCRIPTION & OPERATING CONDITIONS
DESCRIPTION
The slip is essential to the functioning of the coupling: there could
not be torque transmission without slip! The formula for slip, from
which the power loss can be deduced is as follows:
The TRANSFLUID coupling (K series) is a constant filling type
comprising three main elements:
1 Driving impeller (pump) mounted on the input shaft.
2 Driven impeller (turbine) mounted on the output shaft.
3 Cover, flanged to the output impeller, with an oil-tight seal.
The first two elements can work both as pump and/or turbine.
slip % =
input speed – output speed
x 100
input speed
OPERATING CONDITIONS
The TRANSFLUID coupling is a hydrokinetic transmission. The
impellers perform like a centrifugal pump and a hydraulic turbine.
With an input drive to the pump (i.e. electric motor or Diesel
engine) kinetic energy is transfered to the oil in the coupling. The
oil moves by centrifugal force across the blades of the turbine
towards the outside of the coupling.
This absorbs the kinetic energy and develops a torque which is
always equal to input torque thus causing rotation of the output
shaft. The wear is practically zero since there are no mechanical
connections.
The efficiency is influenced only by the speed difference (slip)
between pump and turbine.
In normal conditions (standard duty), slip can vary from 1.5%
(large power) to 6% (small power).
TRANSFLUID couplings follow the laws of all centrifugal machines:
1 Transmitted torque is proportional to the square of input speed;
2 Transmitted power is proportional to the cube of input speed;
3 Transmitted power is proportional to the fifth power of circuit
outside diameter.

FITTED ON ELECTRIC MOTORS
Any drive system using a Transfluid fluid coupling has the
advantage of the motor starting without load. Figure 2 compares
the current demands of an electric motor when the load is directly
attached verses the demand when a fluid coupling is mounted
between the motor and load. The colored area shows the energy
that is lost, as heat, during start-up when a fluid coupling is not
used. A Transfluid fluid coupling reduces the motorʼs current draw
during start-up thus reducing peak current demands. This not only
reduces power costs but also reduces brown outs in the power grid
and extends the life of the motor. Also at start-up, a fluid coupling
allows more torque to pass to the load for acceleration than in
drive systems without a fluid coupling.
TRANSFLUID COUPLING FITTED ON ELECTRIC MOTORS
Three phase synchronous squirrel cage motors are able to supply
maximum torque only near 100% synchronous speed. Direct
starting the system utilizes the most current. Figure 1 illustrates the
relationship between torque and current. It can be seen that the
absorbed current is proportional to the torque only between 85%
and 100% of the synchronous speed. With a motor connected
directly to the load, there are the following disadvantages:
– The difference between available torque and the torque required
by the load is very low until the rotor has accelerated to between
80-85% of the synchronous speed
– The absorbed current is high (up to 6 times the nominal current)
throughout the starting phase causing overheating of the
windings, overloads in the electrical lines and, in cases of
frequent starts, major production costs.
– Oversized motors are required by the limitations indicated
above.
Figure 3 shows two curves for a single fluid coupling and a
characteristic curve of an electric motor. It is obvious from the stall
curve of the fluid coupling (s=100%) and the available motor
torque, how much torque is available to accelerate the rotor of the
motor (colored area). In about 1 second, the rotor of the motor
accelerates passing from point A to point B. The acceleration of the
load, however, is made gradually by the fluid coupling, utilizing the
motor in optimal conditions, along the part of the curve between
point B, 250% and point C, 100%. Point C is the typical point of
operation during normal running.
To limit the absorbed current of the motor during the acceleration
of the load, a Y-∆ (wye – delta) starting system is frequently used
which reduces the absorbed current by about 1/3 during starting.
Unfortunately, during operation of the motor under the delta
configuration, the available torque is also reduced by 1/3 and for
machines with high inertias to accelerate, oversizing of the motor is
still required. Finally, this system does not eliminate current peaks
originating from the insertion or the commutation of the device.

DELAYED FILL CHAMBER
ADVANTAGES
Fluid couplings with single or double delay fill chamber provide
very smooth start-ups with low start-up torque transmission, and
this makes them excellent for applications with high inertia loads
and for use on belt conveyors.
The single size chamber is available from size 11CK and above.
The double size chamber is available from size 15CCK and above
TRANSFLUID FLUID COUPLINGS WITH A DELAYED FILL
CHAMBER
With the standard circuit in a maximum oil fill condition, fluid
couplings may transmit over 200% of the nominal motor torque. It
is possible to decrease the starting torque down to 160% of the
nominal torque, by decreasing oil fill. This, however, leads to
higher slip and working temperature in the fluid coupling, during
the steady running conditions.
The most convenient solution to provide lower starting torque while
maintaining low slip at steady running is to provide a delayed fill
chamber mounted on the main circuit. This chamber holds a
percentage of the oil which at start-up is gradually released into the
main circuit through calibrated bleed orifices as the coupling
spins. For couplings sized 15CK and above these orifices are set
in externally mounted valves.
The external mounting provides easy adjustment of the orifice size
which controls starting time and the maximum transmitted torque.
When the coupling is at rest, the delay fill chamber contains a
percentage of oil quantity in the main circuit (Fig. 4a). This
reduces the torque the coupling transmits and allows the motor to
quickly reach its steady running speed, as if it was started
without load.
As the coupling accelerates, the oil flows from the delay fill
chamber to the main circuit (Fig. 4b) at a rate proportional to the
couplingʼs rotational speed.
The oil continues to transfer from the delay fill chamber to the main
circuit emptying the delay fill chamber. Once all the oil is in the
main circuit (Fig. 4c) the coupling is then transmitting 100% of the
motor torque and the minimum slip value is reached.
With a single delay fill chamber, the ratio between starting and
nominal torque may reach 150 %. This ratio can be reduced to 120 %
with a double delay fill chamber. This lower start-up torque
results from a smaller amount of oil in the main circuit due to more
oil in the bigger delay fill chamber.
SUMMARY OF THE ADVANTAGES GIVEN BY FLUID
COUPLINGS:
– Very smooth start-ups
– Reduction of absorbed current during the starting phase: the
motor starts with very low load
– Protection of the motor and the driven machine from jams and
overloads
– Utilization of asynchronous squirrel cage motors instead of
special motors with soft start devices
– Longer life and up time of the whole drive train, thanks to the
protection provided by the fluid coupling
– Energy saving, due to current peak reduction
– Limits starting torque to 120% with a double delayed fill
chamber
– Same torque at input and output: the motor can supply the
maximum torque even when load is jammed
– Torsional vibration absorption for internal combustion engines,
thanks to the presence of a fluid as a power transmission
element
– Possibility to achieve a high number of start-ups, or reversal of
the rotational direction.
– Load balancing with dual motor drive: fluid couplings
automatically adjust load speed to the individual motorʼs speed
– High efficiency and minimum maintenance
– Viton rotating seals and O-rings

RECOMMENDED OIL AND QUANTITY SAFETY DEVICES
OIL FILL
Transfluid fluid couplings are generally delivered without oil.
Therefore, it is necessary to follow the filling procedures listed
below :
1 - For a fluid coupling mounted on a horizontal shaft, turn the
coupling body until the appropriate fill mark is at the vertical (12
oʼclock) position. These marks are raised “X”, “1”, “2”, “3”, “4”
that are part of the cast aluminum housing of the coupling Fig.
5. This will place the two oil fill plugs (one on each side of the
coupling) near the 2 oʼclock position.
2 - Remove both plugs, if access permits, and fill until oil overflows
from the fill hole(s). Install both plugs and rotate the coupling
slowly by hand to insure no air pockets are trapped in the fill
area. Reposition the coupling as before and add more oil if
needed. (NOTE: Removing both plugs allows one hole to vent
air as the other is used to fill the coupling).
3 - Reinstall both plugs using non-locking thread sealant as
needed to prevent leaks. Do not over tighten the tapered fill
plugs because they will crack the aluminum housing.
4 - The fill marks allow operators to correctly fill the coupling,
without using any measuring tools, and they also provide
reference points if the quantity of oil needs to be changed to
improve the softness of the start or reduce the slip at steady
running.
5 - For normal operating conditions, use only ISO HM32 hydraulic
(or the equivalent SAE 10W non-detergent motor oil). At low
ambient temperatures (near 0°C), it is recommended to use
ISO FD 10 (or equivalent SAE 5W) oil.
6 - For fluid couplings mounted on vertical shafts, use the oil
quantities listed in Tab. E below.
7 - NOTE : Maximum fill quantities cannot exceed the
following fill positions (quantities):
A) For the “K” series couplings – “X”
(i.e. for a 21K max fill is 19 liters)
B) For the “CK” series couplings – “2”
(i.e. for a 21CK max fill is 23 liters)
C) For the “CCK” series couplings – “3”
(i.e. for a 21CCK max fill is 27.3 liters)

SAFETY DEVICES
FUSIBLE PLUG
In case of a load lock-up or high slip in the fluid coupling the oil
temperature in the coupling will reach very high levels. This heat
damages the seals causing them to leak.
To avoid this problem Transfluid uses melt-out or fusible plugs to
release the oil when the the temperature reaches certain set
points. Once the coupling is empty, it can neither transmit power
or create internal heat. The standard fusible plug melts out at
280°F ± 5° (other temperatures available are 250°F and 390°F).
SWITCHING PIN
For applications where the release of oil through the fusible plug
is not acceptable, Transfluid provides a switching pin device. This
device has a meltout ring that releases a pin which slides out and
trips a relay cam switch. The relay provides a signal that can be
used to either stop the power source or send out an alarm. No oil
is released from the coupling when this device activates, and the
pins are available to trip at the two fusible plug temperatures.
Page 25 provides a more detailed description of this device.
ELECTRONIC OVERLOAD CONTROLLER
This device consists of a proximity sensor, speed controller
panel, and (as an option) an LED rpm readout panel. The sensor
measures the fluid coupling output speed and when this speed
falls below a settable threshold in the control panel, a signal is
produced that can be used for an alarm or as a power source
shut down. This device does not require any replacement parts
when it trips. It only requires that the control panel be reset, and it
is ready for reuse. Page 26 provides a more detailed description.
INFRARED TEMPERATURE CONTROLLER
This device consists of an infrared heat sensor and control panel
with temperature readout display. Like the proximity sensor
above, no contact with the coupling is required and the controller
has two settable thresholds at which an alarm or a shut down
signal is produced. Since this device monitors heat it is the most
effective safety device for preventing heat damage to a fluid
coupling. Also, like the speed controller above, this unit can be
reset and reused without replacements parts. Page 27 provides
more details.

SWITCHING PIN DEVICE
This device includes a percussion fusible plug installed on the
taper plug pos. 13 (Fig. 6).
The percussion fusible plug is made of a threaded plug and a pin,
held by a fusible ring, coming out due to the centrifugal force
when the foreseen melting temperature is reached.
Such increase of temperature can be due to overload, machinery
blockage or insufficient oil filling. The pin, moving by approx. 16
mm, intercepts the cam of the switch to operate an alarm or
motor trip signal.
After a possible intervention and removal of the over-temperature
cause, this device can be easily restored with the replacement of
the percussion plug or even the fusible ring following the specific
instructions included in the instruction manual.
With external wheel as driver, as indicated in Fig. 6, the
percussion plug operates in any condition, while in case of driven
external wheel it can operate correctly only during an increase of
slip due to overload or excessive absorption.
It is possible to install this system on all fluid couplings starting
from size 13K even when it has not been included in the initial
supply, by asking for a kit including percussion fusible plug,
gasket, taper plug, counterweight for balancing, glue and
installation instructions.
In order to increase the safety of the fluid coupling a standard
fusible plug is always installed with a set temperature greater
than that of the percussion fusible plug.
For a correct operation, please refer to the instructions relevant to
the standard or reverse installation described at page 28.

OPERATION
OVERLOAD CONTROLLER
Fig. 7
When load torque increases, slip also increases and output
speed consequently decreases.
The said speed variation can be measured by means of a sensor
sending a pulse train to the speed controller. If the rotating speed
goes lower than the set threshold (see diagram) on the controller,
a signal is given through the activation of the controller s relays.
The device has got a “TC” timer with a blind time before starting
(1 - 120 s) avoiding the alarm intervention during the starting
phase, and another “T” timer (1 – 30 s) preventing from
undesired relay intervention during sudden changes of torque.
The device also provides a speed proportional analogic output
signal (0 – 10 V), to be forwarded to a display or a signal
transducer (4 – 20 mA).
Standard supply is 230 V ac, other supplies are available upon
request: 115 V ac, 24 V ac or 24 V dc, to be specified with the
order.

This is a non contacting system to check fluid coupling
temperature. It is reliable and easily mounted.
It has 2 adjustable thresholds with a logical alarm on the former,
and a relay alarm on the latter.
A
The proximity sensor must be positioned near the fluid coupling
outer impeller or cover, according to one of the layouts shown in
Fig. 9.
It is adviced to place it in A or C positions, as the air flow
generated by the fluid coupling during rotation helps to remove
possible dirt particles that may lay on the sensor lens.
The distance between the sensor and the fluid coupling must be
about 15-20 mm (cooling fins do not disturb the correct operation
of the sensor).
To avoid the bright surface of the fluid coupling reflecting light and
producing an incorrect temperature reading, it is necessary to
paint the surface, which is directly facing the sensor, a flat black
color (a stripe of 6-7 cm is sufficient).
The sensor cable has a standard length of 90 cm. In the case
where, a longer cable is required, use one that is twisted and
shielded as per type “K” thermocouples.

REVERSE MOUNTING
Driver outer impeller
Minimum possible inertia is added to the motor, which allows it
to accelerate more quickly.
The outer impeller, being directly connected to the motor,
reaches synchronous speed at once. Ventilation is therefore
maximum from the beginning.
If a braking system is required, it is convenient and easy to
install a brake drum or disc on the flex coupling.
The outer impeller and cover are connected to the motor, it is
possible to manually rotate the coupling to check
alignment and oil level, and for refilling.
The delayed fill chamber, when present, is fitted on the driven
side. The rotating speed of the chamber gradually increases
during start-up, thus leading to a longer starting time, given the
bleed orifices diameters are not changed.
The delayed fill chamber is fitted on the driver side, and
reaches the synchronous speed in a few seconds. Oil is
therefore centrifuged into the main circuit gradually and
completely.
Flex coupling is protected by the presence of the fluid coupling in
front of it, and therefore this configuration is fit for applications
with frequent start-ups or reversals.
The switching pin operation is always assured, as the
outer impeller, always rotates because it is mounted on the
driver shaft.
